Nexflow Smf runs on your own machine — the client starts it, so there is no endpoint to ping. 27 installs a week from npm. Last commit 20 Mar 2026.
Smart Meta-Facilitator for x402 payments on Base: route, verify, and settle payments.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 9 August 2026. No other catalogue keeps this.
Today is the operative word: we check Nexflow Smf every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
